Abstract

An experimental study has been conducted using 50%/50% volumetric mixture of water-ethylene glycol to assess its use for cooling of automotive power electronics using jet impingement. This study focuses on the utilization of a variable area jet discharge manifold to enable improved spent fluid management. Tests were conducted using expanding manifolds at angles up to 10 degrees, volumetric flow rates of up to 18.9 lpm (5.0 gpm), and inline arrays of jets. Several geometric parameters were studied. A unique method of translation in two orthogonal axes was used to provide experimentally measured two-dimensional maps of heat transfer coefficient. The heat source used simulated a power electronics module producing up to 500 W. The results for the expanding-area discharge manifold are benchmarked against a standard, constant-area manifold to show the efficacy of this spent fluid management method. Area-averaged heat transfer coefficients as high as 13.5 kW/m2K have been measured. Results for water-ethylene glycol are benchmarked against results for water, reported earlier.
